Is overdoing an apology just as annoying as the jerk that never told you sorry?

If someone wrongs you and they don't apologize, they're jerks. What about if they do apologized, you forgive them but from time to time, they continue apologizing? They feel they can't forgive themselves that they apologize repeatedly.

I met someone like that once. There was a point I wanted to talk about other topics and they brought back that moment, how they feel like apologizing again and again. Is that just as annoying too? Logically all extremes in life are bad.

If you never apologize when you're wrong, then obviously you're selfish. But if you apologize too much, that can't be good either.
